I would test it but I'm running XP, and XP isn't allowed to the party. This seems to have been what was recently used to reclaim the "fastest card evar" crown. "What we notice is that the beta Catalyst 12.11 driver does, in fact, deliver a massive performance boost in a majority of the games we're testing. Nvidia only manages to maintain an advantage in long-time strongholds like Battlefield 3 and Batman: Arkham City, even though AMD jumps from 25 to 30 percent in Battlefield 3, practically making it a draw..."

I have seen a 25% boost in performance while running Einstein/OpenCL via an AMD 7970. The increase was with Linux beta driver 12.11 over driver 12.10 and APP SDK 2.7. I have not tested with Seti yet.

So far, I very much like the performance of the 7970 with driver 12.11. Plus the PCI-E 3.0 support works out of the box in Linux and Windows with the socket 2011 processors which is a nice bonus. No hacks are required like with the NVIDIA drivers and there is complete stability.

Yes, it's in the first post "Catalyst 12.11", which at this point, is still in Beta. You can find it here AMD Catalyst™ 12.11 Beta Driver Or, if you don't like Betas, you can install the AMD Catalyst™ 12.10 Driver from here Graphics Drivers & Software , then install the 2.8 Runtime from here Windows Vista® SP2 / Windows® 7 . Note there are 3 parts to that SDK, you only need the RunTime Part. Obviously, the easiest thing to do is install the "Catalyst™ 12.11 Beta Driver"...

Since you have installed the Catalyst™ 12.11 Beta Driver, as in this article, have you noticed an approximate 25% performance increase?

I've d/led the files. I'll install in the morning and see how they run

Thanks. I was getting all worked up about upgrading to Win 8 until I remembered they are working on a version of the GPU apps that work on a Mac. I do have Lion installed on this machine. I think I'll just wait for a Lion version of the SETI GPU apps instead of rushing into some new flanged Windows OS. I'll have to think about it...

2 all who upgrade their drivers looking for speedup:
don't forget to delete binary cached kernels from project directory then. App will recompile them with new driver and then will have a chance to recive some speedup from better compiler in new driver.
But beware, Cat 12.10 (for example) known to produce invalid binaries (results can not validate). Cat 12.11 beta 8 looks clean though.SETI apps news
We're not gonna fight them. We're gonna transcend them.

My AMD system was finally able to pickup a few AP tasks. The processing time via driver 12.11 appears to be faster than what I am seeing via my GTX 580s but it is hard to tell for sure as processing time varies significantly from one task to another. GPU load ranges from 59-77%.
